DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Reference is now made to FIG. 1, which is a simplified partially cut-away pictorial illustration of a lighter constructed and operative in accordance with a preferred embodiment of the present invention. As seen in FIG. 1, the lighter preferably comprises a generally elongate body 10 defining a partially bifurcated liquid fuel reservoir 12. Sealingly attached to body 10 at opposite ends thereof are a pair of lighter head assemblies 14 and 16, which communicate with respective portions 18 and 20 of fuel reservoir 12 via respective liquid fuel feed conduits 22 and 24.

Conduits 22 and 24 define respective first ends 26 and 28 which lie within respective portions 18 and 20 of fuel reservoir 12 and respective second ends 30 and 32 which communicate, via respective fuel supply valves 34 and 36, with respective fuel outlets 38 and 40. Assemblies 14 and 16 also preferably comprise respective finger operated spark generator subassemblies 42 and 44 and thumb operated fuel valve opening levers 46 and 48.

It is a particular feature of the present invention that notwithstanding failure of one of the lighter head assemblies 14 and 16, the lighter and the remaining fuel therein need not be discarded, inasmuch as the other of the head assemblies 14 and 16 may be employed.

Reference is now made to FIG. 2, which is a simplified partially cut-away pictorial illustration of a lighter constructed and operative in accordance with another preferred embodiment of the present invention. As seen in FIG. 2, the lighter preferably comprises a generally elongate body 110 defining a partially bifurcated liquid fuel reservoir 112. Sealingly attached to body 110 at a top surface 113 thereof and overlying opposite sides thereof are a pair of lighter head assemblies 114 and 116, which communicate with respective portions 118 and 120 of fuel reservoir 112 via respective liquid fuel feed conduits 122 and 124.

Conduits 122 and 124 define respective first ends 126 and 128 which lie within respective portions 118 and 120 of fuel reservoir 112 and respective second ends 130 and 132 which communicate, via respective fuel supply valves 134 and 136, with respective fuel outlets 138 and 140. Assemblies 114 and 116 also preferably comprise respective finger operated spark generator subassemblies 142 and 144 and thumb operated fuel valve opening levers 146 and 148.

It is also a particular feature of this embodiment of the present invention that notwithstanding failure of one of the lighter head assemblies 114 and 116, the lighter and the remaining fuel therein need not be discarded, inasmuch as the other of the head assemblies 114 and 116 may be employed.

Reference is now made to FIGS. 3A and 3B, which are respective side and edge view illustrations of a cigarette lighter constructed and operative in accordance with a preferred embodiment of the present invention in a first operative orientation, and to FIGS. 4A and 4B, which are respective side and edge view illustrations of the cigarette lighter of FIGS. 3A and 3B in a second operative orientation. Similarly to the embodiment of FIG. 1, the cigarette lighter of FIGS. 3A-4B preferably comprises a generally elongate body 210 defining a partially bifurcated liquid fuel reservoir 212. Sealingly attached to ends of body 210 are a pair of lighter head assemblies 214 and 216, which communicate with respective portions 218 and 220 of fuel reservoir 212 via respective liquid fuel feed conduits 222 and 224.

Conduits 222 and 224 define respective first ends 226 and 228 which lie within respective portions 218 and 220 of fuel reservoir 212 and respective second ends 230 and 232 which communicate, via respective fuel supply valves 234 and 236, with respective fuel outlets. Assemblies 214 and 216 also preferably comprise respective finger operated spark generator subassemblies 242 and 244 and thumb operated fuel valve opening levers 246 and 248.

It is also a particular feature of this embodiment of the present invention that notwithstanding failure of one of the lighter head assemblies 214 and 216, the lighter and the remaining fuel therein need not be discarded, inasmuch as the other of the head assemblies 214 and 216 may be employed.

As distinguished from the embodiment of FIG. 1, the lighter assemblies 214 and 216 of the cigarette lighter of FIGS. 3A-4B also comprise respective selectably raisable wind shields 250 and 252, formed with respective side wall apertures 254 and 256 for receiving a cigarette to be lighted by a flame emanating from respective fuel outlets.

Operation of the cigarette lighter of FIGS. 3A-4B may be understood from a consideration of FIGS. 5A, 5B and 5C, which are pictorial illustrations of the use and operation of the lighter of FIGS. 3A-4B and which illustrate raising of windshield 250, generating a flame by operating spark generator subassembly 242 and lighting the end of a cigarette extending through side wall aperture 254 of wind shield 250.
